HENRY MATTES, OF NEW YORK, N. YL, ASSIGNOR OF ONE-HALF T0 GEORGE E. POEHN,

OF NEW YORK, NY.

PORTABLE KNOCKDOWN SHELTERED COT.

mamon T0 all whom it may concern Be it known that l, HENRY MATTEs, a citi` zen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Portable Knockdown Sheltered Cots; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.y

My presentv invention relates to beds for sleeping, resting or lounging purposes,'but has reference more particularly to portable, knockdown, sheltered cots for military or civil uses such as required by state militia and the regular army, or by camping and hunting expeditions, wherev great strength, extreme lightness, compactness and durability are necessary.

As a further object this invention contemplates the'production of means whereby occupants of cots maybe effectually protected from inclemencies of the weather, and from contact with the ground. v

As a further object my present invention contemplates certain changes and improvements upon the structure represented by U. S. Letters Patent No. 1,020,998, issued to me under date of March 26, 1912. y

Other objects and advantages will be apparent to persons skilled in the art to which my improvements relate.

` The invention will be hereinafter particularly described and pointed out in the claims following.

In the accompanying drawings which form part of this application for Letters Patent, corresponding numerals refer to like parts in the several views upon both sheets whereon':

Figure 1 is a perspective view of my invention with one half of its canopy top thrown back disclosing the structural frame and hammock or cot bottom in relative positions. Fig. 2 is a plan view'of the cot frame with the canopy top removed, and the hammock or cot bottom, as also one end of the canopy frame, broken away. Fig. 3 is a centrallongitudinal sectional view through. a portion of one side rail of the cot frame. Fig. 4 isa horizontal sectionalfview, taken at right angles to section ofthe preceding figure, thrc'n'igh one corner-.--ofxthe frame.

Fig. 6 is a longitudinal through the upper end of one corner post,

and one tubular member of a superimposed canopy frame, a fragment of the corresponding canopy frame member being shown in full lines. Fig. 8 is a detached fragmentary .disconnected view in perspective showing means for connecting at one end the canopy frame members including a ridge-rod common to all of said members. F ig. 9 is also a fragmentary view showing a longitudinal central section of means for coupling together the individual sections of a sectional ridge-rod, and, Fig. 10 is a collective view inl side elevation of all telescopic tubular members forming one quarter of the entire cot frame and canopy frame members.

, Reference being had to the drawings and numerals thereon, 1 indicates vertical corner posts of which therearefour constituting the chiefv support of the structure. rllhese posts like all tubular members of this invention are preferably made of aluminum for the sake of lightness, with steel coupling ends for great strength, but obviously the material or materials employed is wholly optional and forms no part of the present invention. The said posts 1 are provided with studs 2 or protruding buttons, similar to carriage buttons, at regular and predetermined intervals throughout their entire length, for purposes later to appear; and at points intermediate of their ends, but of uniform height upon each post 1 is brazedv or otherwise permanently secured a coupling box 3 having rightvangular hollow eXtensions constituting transverse and longitudinal couplings 4 and 5 respectively of tubular form'. l

p Into each of the four transverse coupling sockets 4, as by a snug but removable slide fit, is placed one end of a'transverse endtube 6 slightly curved at 7 `forpartiallyembracing its corner post 1 as lshown by Figs. 4 and-10; and detachably coupled at its opby one of said members., These four transverse members 6 joined together and coupled to their respective corner posts 1 as aforesaid constitute head and foot end rails of the cot fra-me. Similarly into the four longitudinal coupling sockets 5 of coupling [boxes 3 are placed the ends of side exten- "sions 9 each slotted longitudinally as at 10 to receive a pin 11 rising vertically from the interior of'said sockets 5 as shown by Figs. 3 and 4, to prevent rotation, and each simiy larlyslotted or grooved in its opposite end as at 12 to `receivea tongue 13 projecting Afrom adjacent intermediate sections 14. The .15

said' intermediate sections 14, oftubular form,'are detachabl joined, .as indicated in Fig. 3 by means o a ferrule. 15 bra-Zed or (n otherwise secured to one of said sections and adapted to telescope with the other of said intermediate sections. Thesetubular telescopically arranged members 9, 14, 14 and 9 combine to form longitudinal or side rails y lof the'cotfframe at the center of which the intermediate sections 14, 14 arel coupled X- t.

gether as best shown by Figs. 3 and 5. the center of saidlongitudinal or side rails .ofthe cotk frame there are provided corresponding intermediate supporting legs 16v which are removably affixed to both longitudinalside rails at this point. These intermediate legs 16 are each provided with a T- head 17 of a diameter to permit longitudinal movement thereof upon either of the frame sections 14, and are equipped with a vertically actuated bolt 18 normally projected by means of spring 19` in to the inteadapted to snugly receive the bolt 18 afore-f f 8.- l.Goiinectin their points o junction', or apex of the structure, is' a vcentral superimposed ridge-rod said when moved into register therewith andprojected, for the purposeof preventing. ro-

tation of intermediate legs 16 upon frame members 14 as an axis.

permanently secured in place, andl these closures are drilled radially as at 24 from above, at an angle approximatin 45 degrecs, to receive the lowerends o tubular canopy supports 25 which meet overhead, at opposite ends of .the structure, and are joined by tongue and groove connections 26, 27 respectively, as best shown by Figs. 7 andA the said supports 25, 25 at made of four tubular section's28 detachably united-by suitablelslip joints, comprising a projecting-.tubular sleeve or fer-rule 29 `car .ried by one sectionand adapted to enter the adjacentsection snugly as shown by Fig. 9,l

EachV of the four,l corner posts 1 is ycapped by top closures23 The-extreme *ends of said tubular ridge-rod 28 are both equipped with pintles 30 for en- .tering apertures 31 in the uppermost ends of the canopy supports 25 to interlock them inoperative position, and, it 4will be noted, While one ofjsaid pintles is fixed as shown by Fig. 10, the other, as shown byFig. 8, 'is longitudinally movable and normally projected under action of a surrounding coil spring 32 to facilitate the assembling of these parts.` Secured to all four end and side rails of the cot-frame by means of straps and buckles 33 surrounding same,- is a one-piece hammock or cot bottom 34 of rectangular form made of duck, or other durable flexible material, which serves the additionalfunction of securely retaining all sections of the cot frame in position against the possibility of accidental dislodgement,

and affords convenient means of taking up slack at all times. Over the entire frame structure as hereinabove described. is placed a unitary inclosing canopy or tent covering 35, preferably made of light waterproof niaterial, shaped 'in conformity with the general outlines of the frame structure as shown by Fig. l,- and provided with a suitable opening or entrance. In its preferred form this canopy or tent covering 35 is opened vertically at both ends in its transverse center from ridge-rod 28`to the4 ground line,

Abeing equipped with buttons 36 and buttonholes 37 in its overlapping edges as the means of closure when desired, and in addition all four corners of said covering 35 are provided with suitable grummets 38 adapted to buttonrover studs 2 upon corner posts 1.

`One important object of the invention being compactness for purposes of transmisa sionor'storage, the tubular frame members are made of varying diameters adapted to be inserted or nested one `within the other in the order indicated by Fig. 10 of the drawings reading from right to left. With exception only of the two lintermediate legs 16, this Fig. 10 representsall component parts ofl a one-quarter section of the entire frame structure and consequently when knocked Adown and compactly stored,-there are four such sets oftubular parts each nested With- -fplaced in an ordinary dress suit case, or if preferred the metalparts and hammock or cotybottom 34 aswell, may be conveniently enfolded' inthe canopy or tent member 35,

`and carried upon the shoulders of a user. 1tl

will be vnoted also. with what facility the hammock or cot bottoniv 34 may be drawn .-in one ofthe four corner posts 1. As 'thus and` held taut by the agency of the surroundl ing buckles and straps 2.3, at the same time vand'by the same means efectually preventing any -longitudinal movement Ior separation of the tubulary frame members. Itmayi` lmediate section 14 with relation to said rails 9, it is impossible for intermediate legs 16 tov assume anything but a true vertical position when-set up for service. Beyond this the use and operation 'of my improved cot is similar to other cots heretofore in common use. And

Having thus described my invention, what I now claim and desire Ito secure by Letters Patent is: i

l. A knockdown cot of the class describe including in combination a frame having corner posts of enlarged tubular formation, tubular end railsV formed of separable sections of less diameter than the corner posts and detachably supported therein, tubular side rails formed of separable sections of less diameter than the .end rails also detachably supported in said corner posts, vand means including a flexible cot Abottom in a plane with said end and side rails and connected therewith for securing and retaining them in assembled relation and having along at least one of its'four edges'detachable connections.

' I,2. A knockdown cot of the class described including in combination a frame having corner posts of enlarged formation, tubular end rails formed of uniform separable-sections of less diameter than the corner posts and detachably supported therein, tubular side rails each formed of separable sections of varying cross sectional area and of less diameter than the yend rails also detachably supported in said corner posts, a ytubular supporting leg detachably secured to each side rail intermediate of its corner posts, and

means including a removable eXble cot bottom, in a plane with said end and side rails and connected therewith for securing and retaining all of sald railslin assembled four edges detachable connections.

. 3. A knockdown cotof the class ldescribed l including in` combination a 'frame having corner posts of' enlarged tubular formation, tubular end rails formed of separable sections Qf less diameter than the corner posts and detachably supported therein, tubular side rails formed of 'separable sections of less diameter than the end rails also detachably supported in said corner posts, a superimposed cover-supporting frame composed of tubular sectionsl of less diameter than the separable sections of the side rails, including a sectional ridge member, and means including afleXible cot bottom in a plane common to said end and side rails and connected therewith for securing and retaining all parts in operative assembled relation and having along at least one of its four edges detachable connections.

4. A knockdown cot of the class described including in combination a frame having corner posts of enlarged tubular formation, tubular' end rails formed of separable sections of less diameter than Vthe corner posts and detachably supported therein, tubular side rails formed of separable sections of less diameter than the end rails also detachably supported in said lcorner posts, a tubular intermediate supporting leg detachably secured to each side rail by meansv of a surrounding T-head, a spring-pressed bolt normally protruding from each.of said tubular legs into its T -head and adapted to inter; lock with its adjacentside rail, and means including a detachable flexible cot bottom in a plane common to said end and side rails and connected therewith for securing and retaining them in operative assembled relation and havingalong atleast one lof its four edges detachable connections.
